Bridging the Gap: Total Tensile Strength In A Suspension Bridge

by Gregory Timmins

Submitted : Spring 2015

An aspiring architect is in the final stages of designing a suspension bridge meant to span a gorge 44.0 feet across and 24.0 feet deep. If it has already been calculated that the bridge could successfully support a 225kN truck driving along its entire length and given the data provided in Figure 1, what is overall amount of tensile strength of the suspension bridge? Assume a yield stress of 345,000kN/m2 and a resistance factor of 0.95. Ignore deflection and fatigue.
